I'd like to install a MapR Cluster that has 2 node type, master node and data nodes. Is it possible to have MapR Nodes with having any MapR-FS disks?
Hi Juler John Sepnio,
Have you checked out Planning the Cluster - MapR 5.0 Documentation - doc.mapr.com ? Please share your ultimate goal for this cluster. It would help us better to guide you.
Yes I did check out the link about "Planning the Cluster". My ultimate goal is to create a MapR Cluster with HDP Ecosystem and separate the roles of my cluster nodes to Master and Worker Roles.
Master Roles are nodes that would have the master services like HBase Master, YARN Resource Manager, etc.
Worker Roles is where my HBase Regionservers, YARN Nodemanagers and MapR File Servers.
What I want is that I don't want to dedicate Disks to serve as MapR-FS disk to Master Nodes. I cannot achieve my goal using the MapR Installer.
Thank you for additional details. Want to invite Deborah, our cluster admin expert, to join the discussion and offer her recommendation. Thank you.
Some services (like ZooKeeper) can run without storage in the cluster, but they still need some disk space in the local file system. I don't know off the top of my head which others can run without MapR-FS installed. You are correct that the MapR Installer will not work for what you are trying to do: it assumes that all nodes you are installing are using the same disk names for cluster storage.
To install nodes with different disks, you would need to do a manual install, and then run disk-setup on the nodes separately. Here is some information on performing a manual install:
